According to police, William Sherwood, 64, shot and killed John Pratt, a car dealership sales manager who was out test-driving an SUV for trade-in.

Police say Sherwood aggressively followed Pratt down Babcock Street, and even when Pratt slowed down to let Sherwood pass, Sherwood continued to follow closely behind.

At one point, Sherwood slammed into the back of Pratt's vehicle, and then rammed it again as Pratt was getting out of the car, police said.

Witnesses said Pratt grabbed some papers and went to talk to Sherwood, and that's when Sherwood rolled down the window and fired two shots from his vehicle, killing Pratt, police said.

"One car was pulled to the side and is still in that position, and another car was behind it. The driver of the front car got out to approach the driver of the back car and started yelling at him, and the driver of the back car shot him twice. And he's still here. Everybody is still here," said a 911 caller.

A witness approached Sherwood and asked what happened, and Sherwood claimed he was attacked, police said.

Witnesses told police that Pratt appeared agitated but did not act aggressively or attack Sherwood.

After the shooting, w witness told Sherwood to hand over his gun until police arrived.

Boniface Hiers General Manager Bob DiGiacomo said Pratt had worked in auto sales in Brevard County for more than 40 years and was "an absolute saint."

DiGiacomo said employees at the dealership were devastated.

"He's a father who cherished his grandkids and always cherished and spoke highly of his wife. The loss is immeasurable," DiGiacomo said.

Records showed Sherwood has an extensive record of traffic violations dating back to the 1980s. Most of the citations were for speeding.

One neighbor described him as a nice man, while another said he's "worthless, drunk and loony as they come."

Sherwood was charged with second-degree murder and was ordered to be held on a $300,000 bond.

Sherwood remained in Brevard County Jail as of early Sunday. He was scheduled to appear in court on May 2.
